Robert of Hereford

Robert the Lotharingian (died 26 June 1095) was a priest who became Bishop of Hereford following the Norman Conquest of England. His writings serve as one of the best sources for information on the process of compiling the Domesday Book, and he may have introduced the abacus to England.

Life Robert was a native of Lorraine

Robert may have arrived in England by the 1050s, or perhaps after the Norman Conquest. Arguments have been presented on both sides. Robert was ordained as a priest by Wulfstan, Bishop of Worcester sometime before 29 December 1079. Robert was consecrated as the Bishop of Hereford by Lanfranc on 29 December 1079 at Canterbury. but it had little effect on historical writing in England, beyond the use that Florence of Worcester made of it. Robert inserted into his own copy of Marianus, a notice about the Domesday Book survey, that is one of the best sources for information on the process of Domesday. His only other work that survives is a small introduction to Marianus' chronicle that corrects a few errors and discusses computation. and some historians feel he helped introduce it into England. Others, though, disagree and feel that the use of the abacus was known before this time in England. He was good friends with Wulfstan, Bishop of Worcester, and it was Robert who buried the future saint. It may be that Robert gave Wulfstan a copy of Marianus' chronicle, which allowed the monks at Worcester to use it in their own works.

Robert was present at the Council of Rockingham in February 1095, which dealt with the conflict between King William II of England and Anselm, the Archbishop of Canterbury. Robert sided with the king against the archbishop. Afterwards, however, Robert and Osmund, the Bishop of Salisbury, were reconciled with Anselm.

Robert died on 26 June 1095. This was a two-tier chapel of a type reserved for royalty or archbishops in Germany.
